Cloud Deployment – NIST Definition
  Private
Cloud: For use by an enterprise only
  Owned / operated by enterprise IT or 3rd
party
  Public
Cloud: For use by anyone
  Owned / operated / offered by a Cloud
Service Provider
  Hybrid
Cloud: Multiple interoperable Clouds
that enables data and application portability
  Multiple operators

Seamless Hybrid Cloud

With Hybrid Cloud enterprises may have
resources distributed in Enterprise intranet
and one or more Public Clouds

Enterprise should be able to execute apps on
these distributed resources seamlessly as if
they are on the intranet

Manage distributed on-premises and offpremises Cloud resources seamlessly with IT
resources

Seamless Hybrid Cloud Abstraction, Interfaces
and their realization on infrastructure will
facilitate above

Differentiated Quality of Cloud
Services
  QoS
associated with SCL
  QoS abstraction: Platinum, Gold, etc.
applied in aggregate
  QoS abstraction defined based on
Application Classes as defined in RFC 4594
  Example: Multimedia Conferencing
  Loss/Delay/Jitter bound: .001/100ms/
50ms
  DiffServ (DSCP) marking: AF41/42/43


SCL and CLIA abstractions and their realization …
Allows secure and seamless integration of tenant’s
enterprise to Public Cloud
Simplifies Cloud usage by tenants
Allows CSP offer sophisticated SP & Enterprise
grade Cloud services
Allows seamless execution of applications on
resources distributed over Clouds together with
enterprise resident resources
Allows seamless management of Cloud resources
together with enterprise IT resources

Further Work

Abstraction realization in network via network management
systems

CLIA realization via PPVPN (Provider Provided VPN) extension
to support Seamless Hybrid Cloud

Extension to cover multiple CSP

Incorporation in OpenStack (an open source Cloud Stack)

Standardization
  Tenant  CSP, CSP  CSP interoperability, interfaces
  Compute/VM, Storage and Network level interoperability,
interfaces
